I understand what you are saying, I have been using Chuck Cunningham's rc design ideas for years. At the size I am going to use, the enlarged rubber plans structure will be fine for a small electric plane. I hope to start cutting balsa in a few days.

I saw the Merc when you posted the pic, where did you get it?
I used the same picture then converted it to .pdf to be able to scale and tile the plan. It took 643% to get a 45" span.

I plan to use a Esky 400xt and a 10-5 prop and a Rhino 3s 1250mah batt.

The C.C. Mercury has a long fuselage and a short wing and I will probably fly it like a sport plane, barnstorming the local park.

I have - thru a torturous route ( I am not a draughtsman - managed to get a working plan at 24" span available either as DWG or DXF formats. The standard is not CAD standard but is workable to experienced builders.

both these files are about 4Mbs which I think are too large for here - but I will try anyway.

maybe Planeman could work his magic and convert to PFD - I can only read pfd as I dont have the full program - no need and too many $$$$$$

I could also scale up in the dwg and DXF formats ( I favour 48" for dual role - electric free flight and also RC.)

let me know what you want and I will email direct if the forum upload quality not good enough

Hi John.
I know nothing about cad drawing , but I can convert DXF to pdf files.
If you can size the Mercury to 48" as a DXF file, I can convert it and send the files back to you through the thread or to your email.

If Planeman wanted to redraw the Cloud Craft Mercury plan, I couldn't thank him enough. wink...wink...

Cutting parts, planing parts, sanding parts, making spars, just to get to the building part. You "laser cut" scratch builders have it easy Although it doesn't show, I have been busy for the last few hours making a wing kit.
